The Banshee was designed by John Delorean and was meant to compete with the then very popular Ford Mustang which was launched not too long ago but GM decided to cancel the project after they felt that it would pose a threat to the Corvette brand then. Hence, some of its designs have been used in various models under the GM umbrella including the C4 Corvette and the Firebird. The one unit being sold in eBay comes with a 1,500 miles mileage and is as original as you can find and is currently at USD50,000 and rising.
